It has an easy way of integrating with our software so it's nice because we don't have any problems setting up new accounts or anything like that - everything about this product just works automatically without even needing us at all! The only thing I dislike are their fees for upgrades (we use them as part time mail service). Our customers can easily send messages between each other via email which saves me from having too many phone bills every month :p -Easy access via mobile devices.-Reliable service.-Free of cost.-Good customer care support. Not much to dislike about this product. Would definitely recommend to others. I have used this email software for over 5 years now and never had any problem with it till date. It's free of cost, easy to use, reliable and has good customer support. So far so good! I am using this service since last 5 years and never faced any issue or downtime during this time.
